Abstract
Korozija je u današnje vrijeme prisutna na gotovo svim metalnim površinama, a velik problem predstavlja u brodogradnji, zrakoplovstvu i drugim granama industrije. Iako aluminij i njegove legure ne podliježu izrazitoj koroziji u pH području od 4 do 8, morska voda u kojoj je prisutan veći sadržaj kloridnih iona dovodi do pojave rupičaste (pitting) korozije, stoga je zaštita ovih materijala od velike važnosti. Alternativna otapala u koja ubrajamo i prirodna eutektička otapala,pokazala su se kao obećavajuća zamjena za štetna, konvencionalna organska otapalajer su jeftinija, netoksičnai biorazgradiva. Iz tog razloga u ovom radu dan je pregled najčešćih aluminijevih legura, oblici korozije te metode zaštite ovih metala od korozije. Cilj rada bio je ispitati utjecaj prirodnih eutektičkih otapala na koroziju EN-AW 6060 legure u 3% otopini NaCl, a koristile su se gravimetrijska metoda određivanja brzine korozije, elektrokemijska mjerenja gustoće struje korozije, dok su površine uzoraka legure snimljene optičkim metalografskim mikroskopom.
Abstract (english)
Today, corrosion is present on almost all metal surfaces and it is a major problem in shipbuilding, aviation and other industries. Although, aluminium and its alloys are not subject to severe corrosion in the pH range of 4 to 8, sea water with a higher chloride ion content leads to pitting corrosion, so the protection of these materials is very important. Alternative solvents, including natural eutectic solvents, are promising replacement for harmful, conventional organic solvents because they are cheaper, non-toxic and biodegradable. Because of this reason, this paper provides an overview of the most common aluminium alloys, forms of corrosion and methods of protecting these metals from corrosion. The aim of this study was to examine the influence of natural deep eutectic solvents on the corrosion of EN-AW 6060 alloy in 3% NaCl solution, using gravimetric corrosion rate determination method, electrochemical measurements of corrosion current density, while alloy sample surfaces were scanned with optical metallographicmicroscope.
